Qi (器) is a real object or a specific official, position, etc. A qi is something visible, or something one may describe in concrete terms. Every kind of qi has a specific form, function, or capability. Therefore there are clear distinctions between one qi and another. However, a common Dao exists in different qis. The existence of a qi is based on Dao. In terms of human affairs, an individual assumes a particular responsibility suited to his position; but he should go beyond his specific capabilities and strive to adhere to and obtain Dao.
What is above form is called Dao, and what is under form is called “an object.” (The Book of Changes)
Confucius said, “A virtuous man should not possess one skill only.” (The Analects)
Dao disperses and gives birth to tangible objects, and sages who are good at making use of objects of different functions become natural leaders of all officials. (Laozi)
